TreeView checkboxes not maintaining viewstate?

[James]

I have a page with two tabs on it.  When clicking a tab there is an ajax postback.  On the first tab is a tree control with check boxes enabled.  The tree is loaded on page load if it is not a postback.  If I check some boxes in the tree, go to the second tab, then back to the first tab, all the items in the tree are unchecked.  What am I missing?

<telerik:RadTreeView ID="treeView" runat="server" DataFieldID="ID" DataFieldParentID="ParentID" DataTextField="Text" DataValueField="ID" Skin="Outlook" CssClass="tree" CheckBoxes="true" OnClientNodeChecked="ClientNodeChecked" EnableViewState="true">
                                    <DataBindings><telerik:RadTreeNodeBinding CheckedField="Checked" Checkable="true" /></DataBindings>
                                        <NodeTemplate>......

Hello,

Since I was not able to reproduce the described issue, I have attached a sample project that implements a very similar scenario. Could you please clarify what exactly is different in your project? Could you try to reproduce your issue with that project and guide me how can I replicate that behavior at my side. This way I will be able to inspect it at my side and be more helpful.


Kind regards,
